STARTING AND STOPPING MECHANISM FOR AUTOMATICALLY-PLAYED MUSICALINSTRUMENTS.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed March 16, 1917. Serial No. 155,171.

To all whom it may concern:

Be it known that I, WVILLIAM E. HASKELL, of Brattleboro, in the countyof Windham and State of Vermont, have invented a new and ImprovedStartin and Stopping Mechanism for Automatically-Played MusicalInstruments, of which the following is a specification.

The object of the present invention is to provide starting and stoppingmechanism for automatic musical instruments, particularly for pipeorgans which use a perforated note sheet cooperating with an aperturedtracker. The organization is such that when the musical composition hasbeen completed, a special hole in the tracker will be uncovered and, asthe result, the note sheet will be rerolled and the supply of air to thetracker box cut Ofl", and, upon the completion of the rerolling, thererolling mechanism will be cutout of action and the driving motor forthe music roll will stop. The starting mechanism is arranged so that airwill be supplied to the tracker box, and the note sheet motor will beset into action, this starting mechanism being coordinated with thestopping mechanism so that both mechanisms properly act.

The invention is illustrated in the accompanying drawings, whereinFigure 1, is a diagram illustrating the several cooperating parts andshowing their relation to each other. Fig. 2, is a plan view of theinstrumentalities which are manipulated by hand in starting to play.Fig. 3, is an elevation of the starting mechanism. Fig. 4:, is ahorizontal section in the plane indicated by the line 1t in Fig. 3. Fig.5, is a verticalsection of the lower portion of the mechanism shown inFig. 3. Fig. 6, is a vertical longitudinal section of a portion of thetracker box and of the motor which acts to couple either the take uproll or the music roll to the drive shaft. Fig. 7 is a vertical crosssection of a lower portion of the take up roll and the lower portionofthe tracker box. Fig. 8, is a detail view of terminals which cooperatewith a switch carried by the take up roll. Fig. 9, is a vertical crosssection of the tracker box and of a tube bar cooperating therewith. Fig.10, is a. vertical cross section of the wind chest which supplies air tothe motor which drives the music sheet. Fig. 11, is a vertical crosssection of a wind chest which supplies air" to the tracker box.

Fig. 12, is a horizontal section (in the plane indicated by the line12-12 in Fig. 13) of the regulating box which determines the amount ofair supplied to the note sheet driving motor and hence the speedthereof, and which also supplies air to the motor which couples anduncouples the take up roll and the musicroll from the drive shaft.

- Fig. 13, is a vertical longitudinal section of the mechanism shown inFig. 12, the section being in the plan indicated by the line l313 inFig. 12. Fig. 14, is a vertical longitudinal section of the motor whichrestores the starting mechanism to original position and of the wind boxthrough which the action of said motor is regulated. Fig. 15, is detailview illustrating the tempo mechanism.

The invention is shown as applied to a pipe organ in which air underpressure is employed in the various boxes and chests illustrated, and inthose chests wherein air is normally under pressure when the organ is inuse, or is ready for use, the conventional-symbol of a cross within acircle is employed to indicate the normal presence of air underpressure.

A tracker box A, is shown in Figs. 1, 6, 7 and 9. The tracker boxcontains a tracker B, with two rows of holes, the music roll C, and thetake up roll D. In Fig. 9, the note sheet a, is illustrated as extendingfrom the music roll to the take up roll. The tracker box'is providedwith a sliding glass lid 1), at the front which is closed when the organis to be played so as to render the tracker box airtight. After amusicroll C, has been put in place and the leading edge of the notesheet has been attached to the take up roll, the lid is closed and theorgan is ready to start. Starting involves supplying air to the trackerbox, coupling the take up roll to the drive shaft, and supplying air tothe driving motor.

Supplying air to the. tracker b0w.A pipe 1 (Fig; 1) leads from thetracker box to an air supply box E, which is shown in detail in Fig. 11.The pipe 1, communicates with a channel 2, having ports 3 and 4. Port 3,communicates with the supply box E, and port 4:, communicates with theouter air. Two valves 5 and 6, are connected together and to the movableboard of a pneumatic 7, within the supply box. Valve 5, controls theport 3, and valve 6, controls the port 1. The interior of the pneumatic7, is in constant 'communi'cation'with the supply box IE, through ableed passage 8, and likewise is in communication with an outlet pipe 9,having a large cross area as compared with the bleed passage. Theoutletpipe 9, (Fig. 3) is'closed normally (that is when the oris notbeing played) so that the interior that the excess pressure within thesupply box E, collapses the pneumatic 7, so that its movable boardrisesv thereby lifting the valves 5 and 6, hence closing the port 1, andopening the port 3;. Thereupon compressed air flows from the supply boxE, through passage 2, andthe pipe 1., to the interior of the tracker boxready to flow through any hole in the tracker when an, aperture in thenote sheet registers therewith.

The outlet pipe 9, is normally (that is when the organ isidle) closed bya-valve 10 (Fig. 3), which is carried at the lowerend of a sliding pushrod 11,v which at its upper end bears the'word Off as shown in Fig. 2.This push rod 11, is connected by a centrally pivoted lever 12, to asecond sliding push rod which at its upper end bears the word On asshownin Fig. 2. When the organ is idle the push rod 13, is-up and the pushrod 11, is down closing. thevalve 10. To start the organ the push rodl3, isdepressed, thereby elevating the push rod 11, lifting the valve j10, venting the outlet 9, and hence admitting air to the tracker box.-The push rod 13, is yieldingly maintainedin both its upper and lowerpositions by means of a spring 14 bearing upon a doublecam 15 (Fig.3),'carriedby the push rod 13.

O'oupZing the take up roll to the drive shaft.The driveshaft F (Fig.6-), which isrotated through the pinion. c, from the usual motor in awell known way, is mount-- ed to slide longitudinally and at its innerend it carries a pinion cl, which is normally out of engagement with; agear (3, which is permanently coupled to the shaft f, of the take uproll D. The particular intermediate coupling shown between the gear .6,and the shaft 7", is to enable the take up roll to be lengthened orshortened to adapt it to re? ceivenote: sheetsof difierent widths, asset forth in LettersPatent of the United States No. 1,250,165, December13,1917.

In order to connect pinion (Z, and gear 6, the drive shaft F, is movedlongltudmally to the left, as shown in Fig. 6. This longit'udinalmovement is'accomplished by means of a pneumatic G, the movable board ofwhich has an ar1n 16 engaging an annular groove in a collar 17 fixed tothe shaft F.

Theshaft F, is maintained in its normal pos1t1on, shown 111 Fig. 6, bymeans of a spring 18, and the pneumatic G, is normally collapsed. Theinterior ofthe pneumatic communicates through a pipe 19, with the motorregulating box H, as shown in. Figs. 1, 12 h and. 13. If compressed airis admitted to the pipe 19, the. pneumatic G, is expanded, therebymoving the shaft F, to the left (Fig. 6) andconnectlng pinion d and gear6. I As shown inmFig. 13, the .pipe 19, communicates with a compartment20, of the regulating box H. @This compartment is normally vented to theopenv air through port 21,.and communication between it and the supplychamber .22, of the regulating box is controlled by a valve 23. Thevalve 23-, is normally maintained closed by a spring 24:. The stemh25,of the valve 23, slides in guides 26, and it is connected at its extremeouter end, as shown in Fig. 4:, to a lever 27, pivoted at 28. This lever27, has a roller'29, which is pressed by the 'spring 24, against theperiphery of a cam 30, on a vertical. shaft 31, which at its upper end(F ig. 3) has a knob 32, for turning it by hand. Normally, the roller29;, bears upon the-low part of the cam. When the knob 32, is turned,the high part of the cam, 30, encounters the'roller and swings thelever27. (Fig- 4), to the left thereby moving the ;valve 23 (Fig 13) tothe left and hence admitting compressed air from the supply chamber 22,tothe' compartment20,andthence through pipe 19, to the pneumatic G (Fig.6), thereby expanding said pneumatic and coupling the take up roll tothe drive shaft. This same movement of the stem 25, to the left, closesthe venting port 21, by avalve 33, loosely mounted on the stem 25. Asshown'in Fig. 13, the stem 25, has two buttons34c and 35, and it carriesa'spring 36, between button 35, and the valve 33, which presses thevalve 33, against the button 3%, while thestem 25, occupies its normalposition. hen the'valvestem 25,-. is movcdto the left by the cam 30,'the

valve 33, seats'onthe outer face of the box' H and is maintained vieldinl closincr the a be 21 port 21, by the spring 36, since the throw ofompressed air maintains the pneumatic G, 1

exp andet Drioing the note sheet dri the organ isidle the note sheetdrive shaft F,

doesnot; rotate, Hence, to start playing requires setting this shaft inrotation. The shaft F, is rotated by a pneumatic motor of well knownconstruction which is supplied with air from the regulating box H,through the pipe 37 (Figs. 1 and'13). The motor is not shown becausewell known. As shown in Fig. 13, the pipe 37, communicates with acompartment 38, of the regulating box H. This compartment 38,communicates with the supply chamber 22, through an elongated ellipticalport 39, the contour of which is shown in Fig. 12. A slide valve 40,normally closes the port 39. This slide valve 40, itself has a port 41,which is adapted to register with the port 39, in order to supply airfrom chamber 22, to compartment 38. This slide Valve 40, is connected bya rod 42, with a crank arm 43, on the shaft 31, as shown in Fig. 5. Whenthe shaft 31, is turned by its knob 32 (Fig. 3), to start the organ, thecrank 43, moves the rod 42, into proper position to move the slide valve40, so as to'bring port 41, into eifective register with port 39, and,accordingly, air flows from chamber 22, compartment 38, and through pipe37,to the motor which drives the shaft F. 7

When the slide valve 40, is in its idle position with its port 41, shut,as shown in Fig. 13, the compartment 38, is vented to the open airthrough the port 44. Cooperating with this port 44, is a valve 45, on astem 46. An abutment 47, on the slide valve 40, bears against a button48, on the stem 46, and maintains the valve 45, open. Consequently, anyair leakage past the slide valve 40, into the compartment 38, will bedischarged at the vent 44, so that-there will be no accidental orpremature running of the motor. lVhen, however, the slide valve 40, ismoved to the right (Fig. 12) the abutment 47, is moved away from thebutton 7 48, and a spring 49, causes the valve 45, to close the port 44.

After the musical composition has been completed the advance of the notesheet is stopped, the air is cut off from the tracker box, the notesheet is rc-rolled upon the music roll, and the motor is stopped. All ofthis is accomplished automatically and primarily through a special holein the tracker which is uncovered by a registering aperture in the notesheet.

Rewinding the note shect.-The tracker B, has a number of extra holes inaddition to those which control the sounding devices of the organ, asset forth in a companion application for Letters Patent of the UnitedStates Serial Number 143,750, filed January 22, 1917. One of these extraholes is utilized to set in action the rewinding mechanism. It is thehole indicated at50, in Figs. 1 and 6, of the drawings. This hole isadapted to register with an aperture in a wide note sheet; this apertureappearing near the end of the sheet after all of the note playingapertures have terminated. In case a narrow sheet is employed notequipped with apertures to control the sounding devices of the organ,this aperture may be in the form of a notch at the edge of the sheet.This hole 50, in the tracker communicates by a pipe 51 (Figs. 1 and 9),with a channel 52, in a tube bar I. This channel 52, communicates withthe interior of a sliding inverted .cup pneumatic 53, "constituting apneumatic switch. This pneumatic switch is similar to the switch setforth in detail in United States Letters Patent No. 1,297,687, March 18,1919. This pneumatic switch 53, is in permanent electric connectionthrough wire 54, with one pole of an electric generator and itcoiiperates with a yielding terminal 55, which is in electricalcommunication with the opposite pole of the electric generator.Normally, as shown in Fig. 9, and during the playing, the pneumaticswitch 53, is out of contact with the terminal 55. In the event,however, that an aperture in the note sheet registers with the hole 50,in the tracker, compressed air flows through the pipe 51, and channel52, to the interior of the pneumatic 53, thereby lifting it until itmakes contact with the terminal 55, thus closing an electric circuit.The wire 54, of this electric circuit leads to an electro-magnet 56, ofthe solenoid type (Fig. 14), which is inclosed within a wind box J,containing air under pressure. The core of this solenoid 56, isconnected with a valve 57, which is located within a compartment 58,which communicates with the interior of the wind box by passage 59, andport 60. The valve 57, normallyv (when the solenoid 56, is notenergized) closes a passage 61, which communicates by a pipe 62, withthe interior of a time pneumatic 63, located within the wind box. Theinterior of this pneumatic 63, communicates with theopen air through ableed 64, of a much less capacity than the pipe 62. Themovable board ofthe pneumatic 63, is joined by a flexible connector 65, with a valve 66,located in a channel 67, and controlling two ports 68 and 69. 'Port 68,communicates with the interior of the wind box J, and port 69,communicates with the open air. Normally the port 68, is closed, and'the port 69, is open. The channel 67, communicates by a pipe 70, withthe interior of a bellows K. The movable board of the bellows K, isconnected by a link 71, with an actuator 72, consisting of a leverpivoted at 73. This actuator at its upper end is adapted to cooperatewith a stud 74, on an endless chain L. This chain passes around an idlechain wheel 75, and also around a chain wheel 76 (Figs. 1, 3, 4 and 5),at the lower end of the shaft 31. When the tracker hole 50, is exposedand the pneumatic electrode 53 (Fig. 9),. is lifted, the electriccircuit is closed which includes the'solenoid 56. Thereupon, the core ofthe solenoid 56, is lifted and valve 57, is raised thus closing port 60,and establishing communication between the two passages 59 and 61. Therepandingthe bellows. The expansion of the bellows moves the upper end ofthe actuator 72, to the right (Fig. 14) thereby encountering the stud74, moving the run of the chain L, to which the stud 74, is attached, tothe right and hence rotating shaft 31, counterclockwise as the same isshown in Fig. 4. The first result is that the cam 30, is rotated to theposition shown in Fig. 4, so as to bring its low' part opposite theroller 29, on lever 27, whereupon the spring 24 (Fig. 13),

moves the valve stem 25, to the right, thereby closing valve 23,..and.openin valve 33. Hence pipe 19, and pneumatic 6, (Figs. 1 and 6),, arevented and said pneumatic is collapsed by the spring 18. The result isthat the drive shaft F (Fig. 6), is moved to the right therebyuncoupling pinion (Z and gear a. At the same time a crank pin 9, fast onthe shaft F, is brought into register with a crank pin it, on a sprocketwheel 2', which is loose on the shaft F, so that as the shaft continuesto rotate the sprocket wheel 11, is rotated. This sprocket wheel 2', isconnected by a chain 7', to 'a sprocket wheel k, on a shaft Z, which ispermanently coupled to the shaft m, of the music roll C, in the mannerset forth in said Patent 1,250,165. Accordingly, rotation is imparted tothe music roll C, and in the opposite direction to that in which it wasrotated during the playing of.

' the composition. Hence the note sheet is rewound. The backwardrotation of the shaft 31, likewise through the crank arm 43 (Fig,

5), moves the slide valve 40. This move ment of the slide valvefirsttcloses the port 41, but immediately reopens it wide so thatthe.motor is run at high speed during the. rewinding of the note sheet soas'to rewind the note sheet in a minimum length of time. Cutting oflairfrom the tracker b0m.The

chain L, has a second stud. 77, near theichain wheel 76, as shown inFigs. 1, 3 and 4. When the chain L, is moved bythe actuator 72, stud 77encounters the lower end 78, of a bell crank lever (Fig. 3) pivoted'at79. The

upper end 80, is immediately below a padded button 81,1at. the lower endof a stem 82, carriedv by the push rod 13.. When the stud through thevalve 10. The result is that compressed air in the air. supply box E(Fig.

11) flows into the interior of the pneumatic 7, through the bleed 8,vthus equalizing the pressure inside and outside of said pneumatic sothat its movable board and the valves 5-and 6, drop by gravity, aided bythe air pressure on the top of the-valve.6. The result is that the pipe1, and the tracker box A (Figs. 1 and 9) are vented and there is nosounding of the organ during the re-roll of the music sheet. 7

The registration of the aperture in the note sheet with the hole 50, inthe tracker is momentary and, in order to allow timefor the describedaction to take place, the time pneumatic 63, shown in. Fig. 14, isprovided. is again closed by the note sheet, channel 52, (F ig.-9) isvented at the bleed 83, and. the pneumatic53, drops thereby breaking thecircuit which includes the solenoid 56 (Fig; 14). Thereupon valve 57,drops closing the passage 61, and pneumatic 63, is vented by the bleed64, and the movable board of the pneumatic rises under the pressure ofthe. air in the wind box J. In expanding, the movable board of thepneumatic 63, moves farther than the valve 66, thereby slackening theflexible connector 65.. In again collapsing the movable board 63, movesupwardly about half way before tautening the flexible connector 65, andhence without lifting the valve 66, at all. Since the rise of theypneumatic 63, is slow, on account of the smallness of the bleed 64, theport 68, remains wide open longenough to permit thefull expansion of thebellows K. As the pneumatic 63, completes its upward collapse, thetautened connector 65, lifts the valve 66, andcloses the port'68,venting the passage As soon as the tracker hole 50,

67, and the 'bellows K, to: the open air through the port-69. Thebellows K, might then be collapsed by a spring, but this is notessential because the bellows will be col-' lapsed when the push bar 13,is again presseddown to start the organ -again, and the shaft 31, isturned to open valve 23,;md port 41.. When the .push :bar 13, is thuspressed down its button 81, encounters the arm80, of the bell cranklever thus rocking said leverand movingits lower end'78, to

the left, thereby acting upon the stud 77, on thechain L, and'hencemoving that run of the chain to the left and hence partly swing- 7 ingthe actuator 72, to the left and hence partly collapsing .the bellows. 7The subs-e quent turning ofthe knob 32', of the shaft 31,. to bring thetake up roll into action and to start the motor completes the forwardmovement of the chain L, and hence fully collapses the bellows K.

Restoration of selecting mechanism to a0rmaZ.-In the aforesaid companionapplication Serial No. 143,750, filed January 22, 1917, an automaticselecting mechanism under the control of the music sheet to selectstops, couplers, etc., is described, and electrically controlledrestoration means for restoring to normal idle position any stops,couplers, and the like which may be in action on the completion of acomposition. This restoration means includes an electro-magnet. Therestoration mechanism constitutes no portion of the present invention,but there is shown in the accompanying drawings the pneumatic control ofthe circuit which includes the electro magnet of the restorationmechanism of said companion application.

As shown in Fig. 14 the channel 67, communicates with the interior of apneumatic switch. 84 (similar to the switch shown in said Patent No.1,297,687) which is in elec tric communication through a wire '85, withsaid restoration controlling magnet. When compressed air enters thechannel 67, the pneumatic switch 84 lifts and contacts with an electricterminal 86' which is in electrical communication with the opposite poleof an electric battery to that with which the wire 85, is incommunication. This closes the circuit and the restoration controllingmagnet is energized. Thus the same aperture in the note sheet isutilized for the restoration of the stop selecting mechanism, forrewinding the note sheet and for cutting off air from the tracker box.

Stoppag'e of note sheet driving m0t0r. WVhen the note sheet is entirelyrewound upon the music roll C, it is desirable that the driving motorshould stop and automatic means are herein provided for this purpose.The take up roll D, has a recess 11., (Figs. 7 and 9), within which ispivoted at 0, a metallic centrifugal switch M. As soon as the note sheetis wound once around the take up roll the centrifugal switch M, ismaintained wholly within the recess a. WVhen, however, the note sheet isentirely wound ofi' from the take up roll D, the centrifugal switch M,flies outwardly by centrifugal force as indicated in Fig. 7. The take uproll is then rotating in the direction indicated by the arrow in Fig. 7,and the centrifugal switch passes between two spaced elastic electricalterminals 87 and 88 (Figs. 6 and 8), which are secured at their lowerinner ends to the interior of the tracker 'box. These terminals 87 and88, are connected respectively to wires 89 and 90, which lead toopposite poles of an electric generator so that they constituteterminals of an electric circuit. It will be noted from Fig. 7, that theterminals are curved but are not concentric with the take up roll, beingnearer the axis of the take up roll at their free ends than at theirfixed ends. The space between the terminals is large enough for theentrance of the shank of the centrifugalswitch M, this space flaring atits mouth as shown in Fig. 8; but except for this flaring mouth thisspace is narrower than the head of the centrifugal switch. Consequently,as the take up roll continues to rotate, after the centrifugal switchhas entered the space between the terminals, the head of the centrifugalswitch bears with increasing pressure upon the yielding terminals. Notonly is the electric circuit thus completed by the centrifugal switch,but also the terminals act as a brake to stop the rotation of the takeup roll. If the rotation of the take up roll is not stopped by the brakeresistance, it is positively stopped by the head of the centrifugalswitch coming in contact with the block 91, to which the terminals areattached. Accordingly, the take up roll stops with the circuitcompleted.

One of the wires, as 89, leads, as shown in Fig. 1, to an electro-magnet92, of'the so1enoid type carried by the wind chest N. This wind chest isshown in detail in Fig. 10.

The core of the solenoid 92 is connected with a valve 93, which isnormally down and closes a passage 94, leading to the interior of thewind chest N. WVithin this wind chest is a pneumatic 95, the interior ofwhich communicates by a passage 96, with a channel 97 (in which thevalve 93, is located) and to the outer air by a vent 98. A passage 99,communicates with the wind chest N, through a port 100, and with theouter air through a port 101. It also communicates by a pipe 102, withthe compartment 22 (Fig. 13), of the regulating box H. The movable boardof the pneumatic 95, has a stem 103, with valves 104, and 105,cooperating respectively with the ports 100 and 101. The valve 93,normally closes the passage 94, and the interior of the pneumatic isvented to the open air. Consequently, the movable board of thispneumatic is held upwardly by the air pressure within the wind chest N,so that the valve 105, is closed and the valve 104, is open, so that airflows from the chest N, to the regulating box H, and from thence to themotor. When, however, the note sheet is entirely rewound the centrifugalswitch M closes the circuit which includes the solenoid 89, the valve 93is lifted thus closing vent 98 and opening passage 94. Compressed airthen enters pneumatic 95, and the two valves 104 and 105, and themovable board of the pneumatic drop aided by the pressure on the valve105. Consequently, air is no longer supplied to the motor which drivesthe shaft F, and the music roll C, ceases to rotate.

When the organ is to be played, it is necessary to turn the take up rollD, in the direction opposite to the arrow shown in Fig. 7 in order toconnect the leading edge of the notesheet to the take up roll, thisbeing valve 93 (Fig. 10) drops and closes passage 94, Venting theinterior of the pneumatic 95. Thereupon, the air pressure within thewind chest N, collapses the pneumatic 95, thus opening valve 104, andclosing valve 105, so that air is again supplied to the regulating boxH, and the organ is ready to be started again.

Tempo reguZat0n.The shaft 31, has an exposed pointer 106 (Fig. 2),immediately below the knob 32, and this pointer swings above fixedtablets 107 and 108, bearing the inscriptionsReroll and Temporespectively, the tablet 108, also bearing a'series of numbersindicating speed. hen the.or gan is stopped, the knob 32, should beturned so as to leave the pointer 106, in the position shown in Fig. 2,between the tablets 107 and 108. hen thepoin-ter is in this position,the crank arm 43, is in line with the rod 42, as shown in Fig. 15, andthe port 41, of the slide valve 40, is closed, as shown in Fig. 12. Ifnow the shaft 31, should be turned in either direction the valve 40,will be moved forwardly and the port 41, will be opened to a greater orless degree depending upon the extent to which the valve is moved. Asalready pointed out, when the motor K, expands (at the time that therewinding of the note sheet begins) the shaft 31, is rotated so as tobring the pointer 106, opposite the reroll tablet 107, and to asufficient extent to leave the port 41, wide open so that the rerollingof the note sheet is at high speed. In startingthe organ the user .turnsthe knob 32, so as to bring the pointer 106, over the tempo tablet 108,and registering with the particular number on the tempo tabletcorresponding with the tempo number on the note sheet. The farther thatthe pointer is turned to the right over the tempo tablet the more theport 41, is opened and the higher the speed of the note sheet drivingmotor.

Should the user wish to vary'the pre-determined time momentarily it canbe done by the manipulation of the handle 109, shown in Figs. 2, 3 and15. This handle is on a sleeve 110, surrounding the shaft 31. As bestshown in Fig. 15, the sleeve 110, has a crank arm 111, which normallystands in the indicated position there shown, with the handle 1'09occupying the position shown in Fig. 2, between two fixed tablets 112,and 113, which are marked Retard I and Accelt. The crank arm 111, isconnected by a rod 114, with a second slide valve 115, shown in Fig. 12.valve 115, has a port 116, of the illustrated flaring configuration. Theport is narrow at its rear end and flares as it extends forwardly. WVhenthe port 41, is open, its effective area can be changed by moving theslide valve 115. If the handle 109, is swung to the left in Fig. 2, thevalve115, ismoved forwardly thus bringing the narrow .portion of itsport 116, into register with the port 41, hence restricting the amountof air supply to the motor and hence retardingit. ()n the other hand, ifthe handle 109, is moved to the right in Fig. 2, the valve 115, is movedrearwardly thus bringing the wide portion of the port 116, into registerwith port 41, thus permitting the passage of a larger quantity of airand hence accelerating the note sheet driving motor. When the userreleases the handle 109, it is automatically moved to the idleintermediate position illustrated in Figs. 2 and 15, by springs 117 and118, shown in Figs. 12 and 13. Each of these springs extends through alongitudinal slot 119 or 120 (Fig. 12), inthe slide valve 115. If theslide valve 115, is moved rearwardly (that is to the left in Fig. thespring 118, is put under increased tension while the spring 117 playsidly in the. slot 119. Then, when the handle 109, is released, thespring 118, restores the slide valve 115, to its intermediate position.The slide valve cannot overrun backw-ardl-y because it is checked by thespring 117, which acts in opposition to the spring 118. Accordingly, thesprings 117 and 118, between them restore the slide valve to itsintermediate position. Likewise, if the slidevalve 115, is movedforwardly, spring 117 will be put under increased tension and spring 118will play idly in its slot 120; and, when the handle 109 is releasedspring 118, will restore slide valve 115, to its normal intermediateposition. Each spring 117 and 118, is maintained in its normal position(shown in Figs. 12 and 13) by a stop 121.

Rewinding controlled by kand.1t is important that the rewinding of thenote sheet should be under hand control. For example, after starting theplaying of a composition it may be desired to stop it in the middle andto then rewind without completing the composition, or a note sheet maybe used having no aperture or notch regiss tering with the special hole50. This is readily accomplished. To do so the user depresses the pushbar 11 (Fig. 3), thereby closing the outlet pipe 9, by the valve 10.This results in venting the tracker box through pipe 1, and vent 4 (Fig.11), as already described. Hence, there is no further action of thesounding devices because no air can flow through the tracker holes. Theuser then turns the knob 32 (Fig. 2) so This slide 7 as to carry thepointer 106, from over the tempo tablet 108, to over the reroll tablet107 This turns the shaft 31, so that the low part of the cam 30 (Fig.4), is op posite the roll 29 and, thereupon, the spring 24 (Fig. 13),closes the valve 23, and opens the valve 33, thus venting the pipe 19,and the pneumatic G (Fig. 6), so that the spring 18, moves the driveshaft F to the right thereby uncoupling the take up roll and couplingthe music roll C, to the drive shaft F, so that the rewinding begins.After the rewinding has been completed the user turns the knob 32, so asto leave the pointer 106, between the reroll tablet 107 and the tempotablet 108, as shown in Fig. 2, thereby, through crank 43, and rod 42(Figs. 5 and 15), closing the port 41, of the slide valve 40 (Fig. 12),hence cutting off the supply of air to the note sheet driving motor; andopening the valve 45, through the abutment 46, on the slide valve 40,thereby venting the compartment 38, and permitting the escape of any airwhich may leak through the port 41. When the shaft 31, is in theposition shown in Fig. 2 with the pointer 106, between the tablets 107and 108, the roller 29, is on the high part of the cam 30, and close tothe low part of the cam. Hence, any movement of the shaft in eitherdirection from this point opens the port 41, and the rise of the cam inpassing the roller 29, governs the coupling of the drive shaft to thetake up and music rolls. The travel of the note sheet in eitherdirection can be stopped at any time by turning the shaft 31, to theposition shown in Fig. 2.

0pemti0a.To play the organ-the user places the music roll in the trackerbox and connects the end of the note sheet with the take-up roll D, andcloses the lid I), (Fig. 9) of the tracker box. He then pushes down thepush rod 13, (Figs. 2 and 3) thereby elevating push rod 11, (Fig. 3) andlifting the valve 10. This vents the pipe 9, (Figs. 3 and 11) and as theresult the pneumatic 7, collapses thereby opening valve 5, and closingvalve 6, and air then flows from the supply box E, through pipe 1, tothe tracker box as, shown in Fig. 1.

The user then by means of the knob 32, turns the shaft 31, clockwise,thus bringing the pointer 106,'(Fig. 2) over the tempo tablet 108, tothe proper position to secure the desired tempo. This turning of theshaft 31, through the cam 30, (Figs. 3, 4, and 5) acting upon the rod25, closes the valve 33, (Fig. 13) and opens the valve 23, therebyadmitting air from the regulating box to the compartment 20, from whichit flows from pipe 19, to the pneumatic G, (Figs. 1 and 6) therebyshifting the drive shaft F, to such position as to connect it to thetake-up roll I). Also, this forward turning of the shaft 31, rocks thecrank arm 43, (Figs. 5 and 15) from the straight line position, shown inFig. 15, thereby through rod 42, moving the slide valve 40, (Figs. 12and 13) so as to permit the flow of air from the regulating box H,through the pipe 37, to the motor which drives the shaft F. Thus thetake-up roll is driven so as to wind the note sheet thereon and unwindit from the music roll.

After the composition has been played a special hole in the note sheetregisters with the special hole 50, (Fig. 6) in the tracker. Thereuponair flows through pipe 51, (Fig. 9) to the pneumatic switch 53, therebylifting said switch and making electric contact with the terminal 55.This closes an electric circuit which includes the wire 54, (Figs. 1 and14) and the electromagnet 56, shown in Fig. 14. As the result, the valve57, (Fig. 14) is lifted and air flows from the wind box J, throughchannels 59, and 61, and pipe 62, into the interior of pneumatic 63.This pneumatic then expands and the valve 66, drops closing the vent 69,and opening the port 68. Thereupon air from the wind box J, flowsthrough passage 67, and pipe 70, to the bellows K, which expands. Theexpansion of the bellows acting through the lever 72, moves the chain L,and hence rotates the shaft 31, backwardly, that is, in the oppositedirection to that imparted to it by the hand knob 32. This backwardrotation of the shaft 31, removes the high part of the cam 30, from 100the roll 29, (Fig. 4) and, thereupon, the spring 24, (Fig. 13) closesthe valve 23, and opens the valve 33, thus venting pipe 19. Thereuponpneumatic G, (Figs. 6 and l) is collapsed by the spring 18, and thedrive 105 shaft F, is shifted so as to become disconnected from thetake-up roll D, and to become connected with the music roll C.

Likewise, the backward turning of the shaft 31, rocks the crank arm 43,(Figs. 5 110 and 15) to the other side of its straight line with the rod42, thus bringing the pointer 106, (Fig. 2) over the reroll tablet 107.The

swing of the crank arm 43, momentarily closes the slide valve 40, (Figs.12 and 13) and then opens it again so that air still continues to flowto the motor, and the shaft F, (Figs. 1 and 6) still continues to rotatebut now it drives the music roll C, in the proper direction to unwindthe note sheet from the tallileup roll and to wind it onto the music roLikewise, the movement of the chain L, by the bellows K, acts throughthe stud 77, to swing the lever 78, 80, (Fig. 3) thereupon lifting thepush rod 13, and depressing the push rod 11. This closes the valve 10.Accordingly, as shown'in Fig. 11, air from the box E, flows throughpassage 8, into the interior of the pneumatic 7; and the movable boardof this pneumatic drops closing valve .5, and opening valve 6. Thisvents the pipe 1, and the tracker box A, (Fig. 9) so that there is nosounding of the organ pipes during the reroll of the note sheet.

Also, as air flows from the box J, (Fig. 14) to the bellows K, thepneumatic switch .84, is lifted thereupon closing an electric circuitwhich includes the wire 85, thus putting out of commission the organstops as set forth in pending application No. 143,750, filed January 22,1917.

WVhen the note sheet is completely unwound from the take-up roll thecentrifugal switch M, (Figs. 7 and 9) flies out and makes contact-withthe terminals 87, and 88, thereby closing an electric circuit whichincludes wire 89, and magnet 92, shown in Fig. 1.0. Thereupon the valve93, lifts and air flows from the chest N, into the interior of thepneumatic 95. The movable board of this pneumatic then drops closingvalve 104, and opening valve 105. This vents the pipe 102, and hencecuts off the supply of air to the motor. Hence the music roll C, ceasesto-rotate. The lid Z), (Fig.9) of the tracker box can then be opened andthe music roll can be removed and another inserted.

During the running of the motor it can be accelerated or retarded by theuser manipulating the handle 109, (Fig. 15). By doing thisthe slide 115,is moved thereby varying the size of the air passage leading to the port41, (Fig. 12) of the slide valve 40. I At any time during the playing ofa composition the user can stop the playing by turning the knob 32,backwardly until the pointer 106, occupies the neutral position shown inFig. 2. This will close the slide valve 40, (Fig. 13) and open the valve45, thus venting the compartment 38. This stops any flow of air to themotor. Then by turning the knob forwardly again the playing Would beresumed. vOr, at any time either during the playing of the com-positionor upon the completion of a composition on a note sheet unprovided withan aperture to register with the reroll hole 50, in the tracker, theuser may stop the advance of the note sheet and efiect its reroll byturning the knob backwardly until the pointer 106, registers with thereroll tablet (Fig. 2). This results in rerolling the note sheet ontothe music roll. The user should also depress the push rod 11, (Fig. 3)by hand thus closing the valve 10, and venting the tracker bjox. Whenthe rerolling is thus hand-effected, at the close of the rerolling thecentrifugal switch acts in just the same way as when the rerolling isautomatically initiated. In starting to play again, the connection ofanother note sheet to the take-up roll involves turning said rollforwardly and hence disconnecting the centrifugal switch M, from theterminals 87, and 88, and hence regulating box H, with the supply windchest N, the user should also turn the knob 32, so as to move thepointer 106, to the neutral position shown in Fig. 2. This closes theslide valve 40, (Fig. 13) and opens the valve 45, thus venting thecompartment 38,

and hence preventing any leakage of air affooting the motor. In thisneutral position the roll 29, (Fig. 4) is on the low part of the cam 30,as shown in Fig. 4, so that the valve 23, ig. 13) is then closed and thevalve 33, is open so that no air passes to the pneumatic G; V r
